IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent N0. 20,600, dated J une 15,1858.

To all whom 'it may concern.-

Be it vknown that. I, S. W1LLrAMs,of Stock'- ton, in the county of SanJoaquin and State of California, have invented a new and usefulImprovement in Harvesters; and l do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe annexed drawings, forming part of this specification, in the severaliigures of which similar characters of reference denote the same part.

Figure l is' a top view of themachine. Fig. 2 is a vertical section on.r J'. Fig. 3 is a vertical section on y y.

My invention has reference to the manner of adjusting the cuttingapparatus and platform vertically, and-to the manner of giving atemporary elevation to the cutting apparatus for the passage ofobstacles. The details of construction and operation will readily beunderstood from the following description and reference to the drawings.

In this machinethe cutting apparatus and platform are hung between apair oflarge wheels, W W', the former of which gives motion to thecutting apparatus andreel B.. These wheels are attached to short axles AA', secured to the frame F, and bent downward to receive thesuspension-pieces of the finger-bar B, as shown in Fig. 3. Thesuspension-pieces P P have a series of holes, u a", through which boltsb b pass to secure them to theaxle. By

removing the bolts from the holes a and pass.

ing them through the holes a' and the same holes of the axle-arm thecutterbar will be elevated. Having a number of these sets of holes. thevertical position of the cutter-bar may be adjusted to any desiredelevation.

The platform P rests in front upon the nger-bar B, and is supported inrear from the eros-bar of frame F. A

The pole O runs forward from frame F. Beneath side piece of frame F ishinged a draftpiece, D, in the end of which is a double-tree, t, towhich the team is attached, and by which the machine is drawn forward.This piece I) has astandard, E, the bead of which forms the fucrum ofalever, L, attached at one extremity to the frame F, and the otherprovided with a shoe, e. Thedriver,.who is seated at Gr, removes hisfoot from rest H and de forwardmovement of wheel W by the combination ofgear-wheels 'm n m n', the wheel m on the main shaft and m' meshing withit. Wheel n is on the same shaft as m', and meshes with n', thecutter-.bar being connected eccen-y trically with the wheel Zon saineshaft by pitman p. The reel R is also driven from shaft d bylband-connection between pulleys lc 7;. The forward portion of the sidepiece,` f, of frame F is connected with the finger-har by a brace, T,made .up of two sections connected by a swivel-link, .1'. This bringsthe draft directly upon the finger-bar, and the swivehlink serves tokeep the -nger-bar-in its proper position relative to the -frame F.

.The effect of the construction of machine above described is to suspendthe cutting apparatus in an adjustable manner between tw-o large wheels,with nothing near the ground except the finger-bar, which, by meansefthe device before described for lifting the front of the frame, is madeto turn readily about the axis of suspension and facilitate the passageover cradle-knolls without any portion of the machine coming in contacttherewith.

Having described myinvention and the operation thereof, l claim- 1. Thecombination of the draft-piece D,.sde piece, f', of frame, standard E,lever L, and rod connecting the same with the frame, arranged for jointoperation, substantially as described.

2. The short axles A A', depending arms thereof, suspensionpieces P,finger-bar B, and wheelsW W,connected together, substantially asdescribed, in combination with the aforesaid arrangement for elevatingthe fingenbar, the whole being constructed, arranged, and operatingsubstantialiyas and for the purposes set forth.

In testimony whereof I have hereunto signed my name before twosubscribing witnesses.

S. WILLIAMS.
